Description

Technical Field

[0001] This utility model relates to the field of German standard power strips, and in particular to a German standard power strip. Background Technology

[0002] To provide power to more electrical devices, some German standard power strips have two rows of slots for plugs on the front panel. Each slot needs to be equipped with a grounding spring, and each row of grounding clips is connected to a grounding conductive plate. Therefore, German standard power strips with two rows of slots need to have two grounding conductive plates connected in series by wires. The drawback of this type of socket is that the production cost of the parts is relatively high, and the assembly cost of German standard power strips is also relatively high. Utility Model Content

[0003] The technical problem to be solved by this utility model embodiment is to provide a German standard power strip to solve the problem that the existing German standard power strip has a large number of internal ground conductive plates, and multiple ground conductive plates need to be connected in series with wires, resulting in high production costs of components and assembly costs of the power strip.

[0004] The German standard power strip provided in this embodiment of the utility model includes: a housing, which includes a panel, and the panel is provided with two rows of slots, each row of slots being arranged along the length direction of the housing;

[0005] Two rows of ground wire clamps are provided, each corresponding to one of the two rows of slots, so that the ground wire clamp is exposed in each slot.

[0006] The grounding conductive plate includes a main conductive arm and two rows of branch conductive arms. The main conductive arm is disposed inside the housing and located between the two rows of slots. The two rows of branch conductive arms are respectively disposed on both sides of the main conductive arm. Each row of branch conductive arms is correspondingly disposed with each row of grounding clamps, so that each branch conductive arm is connected to a grounding clamp.

[0007] Optionally, the housing includes a back plate disposed opposite to the panel, and the grounding clamp includes a connecting arm and two grounding clamp arms. The connecting arm is installed inside the housing and located on the side of the slot near the back plate. The two grounding clamp arms are respectively bent and connected to both sides of the connecting arm. The two grounding clamp arms pass through the slot wall of the slot to be exposed in the slot. The grounding clamp is integrally formed.

[0008] Optionally, the two ground wire clamping arms have protruding ribs on their facing sides and grooves on their opposing sides that are opposite to the protruding ribs.

[0009] Optionally, the ground wire clamp arm includes:

[0010] The first extension section has one end connected to the connecting arm and the other end extending toward the slot near the slot and toward the other ground wire clamp arm.

[0011] The second extension has one end connected to the other end of the first extension, and the other end extends toward the slot near the slot and away from the other grounding clamp arm.

[0012] Optionally, the housing includes a mounting surface adjacent to the slot and facing the connecting arm, the mounting surface having a plug, and the connecting arm having a contoured insertion hole adapted to the shape of the plug.

[0013] Optionally, it also includes a conductive sheet mounting block, which is used to limit the installation of the neutral wire conductive sheet and the live wire conductive sheet. The conductive sheet mounting block is covered on the side of the connecting arm facing away from the mounting surface to limit the installation of the ground wire clamp.

[0014] Optionally, the conductive sheet mounting block has a mounting beam on the side facing the mounting surface, and the mounting beam has a slot connecting both sides of the mounting beam on the side facing the mounting surface, with the connecting arm passing through the slot.

[0015] Optionally, the conductive sheet mounting block has a notch on one side facing the main conductive arm, and the branch conductive arm passes through the notch.

[0016] Optionally, it also includes a rivet, wherein the grounding clamp is riveted to the branch conductive arm by the rivet.

[0017] Optionally, the German standard power strip also includes a USB module, the USB module including a first USB interface, the first USB interface being connected to the housing and exposed on the housing.

[0018] Compared with the prior art, the beneficial effects of the German standard power strip provided by this utility model embodiment are as follows:

[0019] The German standard power strip provided by this utility model includes a housing, a grounding conductive plate, and two rows of grounding clips. The housing includes a panel with two rows of slots. The two rows of grounding conductive plates are arranged one-to-one with the two rows of slots, so that a grounding clip is exposed in each slot. Specifically, the grounding conductive plate includes a main conductive arm and two rows of branch conductive arms. The main conductive arm is disposed between the two rows of slots, and the two rows of branch conductive arms are respectively disposed on both sides of the main conductive arm. Each row of branch conductive arms is arranged one-to-one with each row of grounding clips, so that each branch conductive arm is connected to a grounding clip. It can be seen that the German standard power strip provided by this utility model only needs to set one grounding conductive plate to connect two rows of grounding clips. Compared with the prior art, which requires a grounding conductive plate for each row of grounding clips, the number of parts is relatively small, which can effectively reduce the production cost and assembly cost of parts.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0047] This utility model embodiment provides a German standard power strip 1000, such as Figures 1-5As shown, the German standard power strip 1000 includes a housing 100, a grounding conductive plate 200, and two rows of grounding clips 300. The housing 100 includes a panel 110 with two rows of slots 111 for plug insertion, each row of slots 111 arranged along the length of the housing 100. The two rows of grounding clips 300 are correspondingly arranged with the two rows of slots 111, ensuring that a grounding clip 300 is exposed in each slot 111. The grounding conductive plate 200 includes a main conductive arm 210 and two rows of branch conductive arms 220. The main conductive arm 210 is located inside the housing 100 between the two rows of slots 111. The two rows of branch conductive arms 220 are respectively arranged on both sides of the main conductive arm 210, each row of branch conductive arms 220 correspondingly to each row of grounding clips 300, ensuring that each branch conductive arm 220 is connected to a grounding clip 300.

[0048] Specifically, since the grounding conductive sheet 200 of this embodiment includes a main conductive arm 210 and two branch conductive arms 220, the main conductive arm 210 is disposed between two rows of slots 111, and the two rows of branch conductive arms 220 are respectively disposed on both sides of the main conductive arm 210. Therefore, each row of branch conductive arms 220 can be configured one-to-one with each row of grounding clips 300. This means that the German standard power strip 1000 shown in this embodiment only needs one grounding conductive sheet 200 to connect two rows of grounding clips 300. Compared with the prior art, which requires one grounding conductive sheet 200 for each row of grounding clips 300, the number of parts is relatively small, which can effectively reduce the production cost and assembly cost of parts, thereby reducing the production cost of the German standard power strip 1000.

[0049] Furthermore, the yield rate of the German standard power strip 1000 shown in this embodiment is relatively high. In existing German standard power strips, the two ground conductive plates need to be soldered together by wires. Issues such as incomplete soldering and breakage of the solder joint due to stress after soldering can occur, leading to a high defect rate in the German standard power strip. The German standard power strip 1000 shown in this embodiment achieves the function of two ground conductive plates in the prior art through a single ground conductive plate 200. Unlike existing technologies, it does not require soldering the two ground conductive plates together with wires. Therefore, issues such as incomplete soldering and breakage of the solder joint due to stress after soldering are eliminated, resulting in a higher yield rate for the German standard power strip 1000.

[0050] refer to Figures 4-7In a specific embodiment, the outer casing 100 includes a back plate 120 disposed opposite to the front panel 110. The grounding clamp 300 includes a connecting arm 310 and two grounding clamp arms 320. The connecting arm 310 is installed inside the outer casing 100 and located on the side of the slot 111 near the back plate 120. The two grounding clamp arms 320 are respectively bent and connected to both sides of the connecting arm 310. The two grounding clamp arms 320 pass through the slot wall of the slot 111 and are exposed in the slot 111. The grounding clamp 300 is integrally formed.

[0051] Specifically, existing grounding clamps all include two grounding arms, but these two arms are separate units, each connected to a grounding conductive plate individually or assembled together before being connected to the grounding conductive plate. Therefore, existing technologies have a relatively large number of components, resulting in higher manufacturing and assembly costs. In contrast, the grounding clamp 300 of this application is integrally molded, thus requiring fewer components and effectively reducing manufacturing and assembly costs, thereby lowering the production cost of the German standard power strip 1000.

[0052] For example, the required strips can be cut from the sheet material first, and then the two ends of the strips can be bent to obtain the one-piece grounding clamp 300.

[0053] refer to Figure 7 In a specific embodiment, the two ground wire clamp arms 320 have a protruding rib 321 on the side facing each other, and a groove 322 opposite to the protruding rib 321 on the side facing away from each other. This arrangement can increase the structural strength of the ground wire clamp 300.

[0054] This embodiment demonstrates a grounding clamp 300 with a raised rib 321 and a groove 322 formed on its surface by applying pressure. Specifically, by applying pressure to the surface of the grounding clamp 300, a groove 322 can be formed at the pressure application position, and a raised rib 321 can be formed on the other side of the pressure application position.

[0055] refer to Figure 4 In some embodiments, the grounding clamp arm 320 includes a first extension 323 and a second extension 324. One end of the first extension 323 is connected to the connecting arm 310, and the other end extends toward the slot of the slot 111 and toward the other grounding clamp arm 320. One end of the second extension 324 is connected to the other end of the first extension 323, and the other end extends toward the slot of the slot 111 and away from the other grounding clamp arm 320.

[0056] Specifically, in this embodiment, the other end of the first extension segment 323 extends toward the slot 111 and toward the other ground clamp arm 320. This arrangement allows the distance between the two ground clamp arms 320 to be less than the diameter of the plug. When the plug is inserted between the two ground clamp arms 320, it will spread the two ground clamp arms 320 apart, thereby giving the two ground clamp arms 320 a tendency to move closer to each other. This tendency will allow the two ground clamp arms 320 to clamp the plug, improving the contact stability between the ground clamp arms 320 and the plug.

[0057] It is worth mentioning that in this embodiment, one end of the second extension segment 324 is connected to the other end of the first extension segment 323, and the other end extends towards the slot of the slot 111 and away from the other ground clamp arm 320. With this configuration, the distance between the two second extension segments 324 has an expanding tendency in the direction of the slot of the slot 111. Therefore, when the plug contacts the second extension segment 324, it can guide the plug to continue to go deeper and promote the two ground clamp arms 320 to move away from each other, thus preventing the first extension segment 323 from jamming the plug.

[0058] refer to Figures 7-9 In some embodiments, the housing 100 includes a mounting surface 130 adjacent to the slot 111 and facing the connecting arm 310, the mounting surface 130 having a plug 131, and the connecting arm 310 having a contoured insertion hole 311 adapted to the shape of the plug 131.

[0059] By implementing this embodiment, when installing the ground clamp 300, the insertion block 131 on the mounting surface 130 can be used to cooperate with the contoured insertion hole 311 on the connecting arm 310 to constrain the position of the ground clamp 300, ensuring that the ground clamp 300 is correctly installed in the preset installation position.

[0060] refer to Figures 7-13 In a specific embodiment, the German standard power strip 1000 also includes a conductive sheet mounting block 400, which is used to limit the installation of the neutral wire conductive sheet 600 and the live wire conductive sheet 500. The conductive sheet mounting block 400 covers the side of the connecting arm 310 facing away from the mounting surface 130 to limit the installation of the ground wire clamp 300.

[0061] It should be noted that the conductive plate mounting block 400 is a component that is present in all existing German standard power strips. It is generally installed on the side of the slot 111 near the back plate 120. The side of the conductive plate mounting block 400 away from the slot 111 has a first mounting groove 430 and a second mounting groove 440. The outer shell 100 of the German standard power strip 1000 contains a live wire conductive plate 500 and a neutral wire conductive plate 600. The live wire conductive plate 500 has a live wire clip 510 that is compatible with the plug, and the neutral wire conductive plate 600 has a neutral wire clip 610 that is compatible with the plug. The live wire clip 510 is installed in the first mounting groove 430, and the neutral wire clip 610 is installed in the second mounting groove 440. The bottom of the first mounting slot 430 and the bottom of the second mounting slot 440 are respectively provided with a first through hole 431 and a second through hole 441. The bottom of the slot 111 is provided with a third through hole 1111 and a fourth through hole 1112, which are respectively opposite to the first through hole 431 and the second through hole 441. When the plug is inserted into the slot 111, one of the prongs will pass through the first through hole 431 and the third through hole 1111 and contact the live wire clamp 510, and the other prong will pass through the second through hole 441 and the fourth through hole 1112 and contact the neutral wire clamp 610. However, in the prior art, the conductive plate mounting block 400 is only used to install the live wire conductive plate 500 and the neutral wire conductive plate 600, and is not related to the installation of the ground wire clamp 300. The ground wire clamp 300 is connected to the outer casing 100 by screws. This also leads to the need for more screws and more parts in the prior art German standard power strip, resulting in higher production and assembly costs for the parts.

[0062] By implementing this embodiment, the insertion block 131 on the mounting surface 130 and the contoured insertion hole 311 on the connecting arm 310 can be used in conjunction with the conductive sheet mounting block 400 to achieve the technical effect of limiting the installation of the ground clamp 300, without the need to use screws to install the ground clamp 300 onto the housing 100 as in the prior art. As mentioned above, the conductive sheet mounting block 400 is a component found in the prior art German standard power strips. Therefore, compared with the prior art German standard power strips, the technical solution of this embodiment eliminates the screws while achieving the limiting installation of the ground clamp 300, and does not add any extra components. As a result, the number of components is relatively small, the production and assembly costs of the components are relatively low, and thus the production cost of the German standard power strip 1000 is reduced.

[0063] refer to Figure 7 and Figure 13 In a specific embodiment, the conductive sheet mounting block 400 has a mounting beam 410 on the side facing the mounting surface 130, and the mounting beam 410 has a slot 411 connecting both sides of the mounting beam 410 on the side facing the mounting surface 130, with the connecting arm 310 passing through the slot 411. This arrangement allows the mounting beam 410 to restrict the grounding clamp 300 from moving away from the mounting surface 130.

[0064] refer to Figure 4 In some embodiments, the German standard power strip 1000 also includes a rivet 700, and the grounding clamp 300 and the branch conductive arm 220 are riveted together by the rivet 700.

[0065] Specifically, riveting has high connection strength and good durability, and the process is simple. Therefore, this embodiment uses riveting to connect the grounding clamp 300 and the branch conductive arm 220.

[0066] refer to Figure 2 and Figure 6 In some embodiments, the German standard power strip 1000 also includes a USB module 800, which includes a first USB interface 810 connected to and exposed in the housing 100.

[0067] By implementing this embodiment, the German-standard power strip 1000 can directly connect to data cables without the need for a power adapter or indirect connection between the power strip and the data cable, resulting in a better user experience.

[0068] refer to Figure 2 and Figure 6 In some embodiments, multiple first USB ports 810 are provided, allowing multiple data cables to be plugged in simultaneously, resulting in a better user experience. For example, when a user places a German standard power strip 1000 at their workstation, they can simultaneously use multiple first USB ports 810 to plug in multiple data cables, one of which is used to power a desktop fan, and another is used to charge a mobile phone or tablet.

[0069] Furthermore, the first USB interface 810 may specifically be configured to have two, three or more, and this embodiment does not limit it.

[0070] refer to Figure 2 and Figure 6 In some embodiments, the USB module 800 further includes a second USB interface 820, which is of a different type from the first USB interface 810. The second USB interface 820 is connected to and exposed in the housing 100.

[0071] By implementing this embodiment, the USB module 800 can be used with data cables of various interface types, improving the user experience.

[0072] It is worth mentioning that there are many specific implementations of the first USB interface 810 and the second USB interface 820, and this embodiment does not limit them. For example, the first USB interface 810 is one of a USB-A interface, a TYPE-C interface, and a Micro USB; the second USB interface 820 is one of the other two of a USB-A interface, a TYPE-C interface, and a Micro USB.

[0073] refer to Figure 13 and Figure 14 In some embodiments, the German standard power strip 1000 further includes a protective component 900, which includes a baffle 910 and a compression spring 920. The baffle 910 includes a first inclined surface 911 that forms an obtuse angle with the third through hole 1111 and a second inclined surface 912 that forms an obtuse angle with the fourth through hole 1112. The first inclined surface 911 is positioned between the first through hole 431 and the third through hole 1111, and the second inclined surface 912 is positioned between the second through hole 441 and the fourth through hole 1112. Each conductive sheet mounting block 400 has a third mounting groove 450 on the side facing the slot 111. A baffle 910 is slidably mounted in the third mounting groove 450 so that when the first inclined surface 911 and the second inclined surface 912 are pressed, the baffle 910 can slide relative to the third mounting groove 450, allowing the first inclined surface 911 to move away from between the first through hole 431 and the third through hole 1111, and the second inclined surface 912 to move away from between the second through hole 441 and the fourth through hole 1112. The German standard power strip 1000 also includes several compression springs 920. The baffle 910 abuts against one of the compression springs 920. When the first inclined surface 911 and the second inclined surface 912 are pressed, causing the baffle 910 to slide within the third mounting groove 450, the compression spring 920 deforms and stores energy.

[0074] By implementing this embodiment, after the plug is inserted into the third through hole 1111 and the fourth through hole 1112, it can press against the first inclined surface 911 and the second inclined surface 912, thereby causing the baffle 910 to move away, allowing the plug to contact the live wire clamp 510 and the neutral wire clamp 610. After the external electrical equipment is unplugged, the compression spring 920 will restore its deformation and cause the baffle 910 to return to its original position. At this time, the baffle 910 will shield the live wire clamp 510 and the neutral wire clamp 610, preventing them from being directly exposed in the third through hole 1111 and the fourth through hole 1112, thus improving the safety of the German standard power strip 1000.

[0075] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
